Which are the correct packages for unstable?

Hi,

Sorry, if what I ask is obvious...
I would like to install KDE for the first time.
I have a notebook running on unstable.

Which is the correct apt source to take the packages from?
Reading the list it seems that most people are suggesting:
deb http://ktown.kde.org/~nolden/kde/woody/i386 ./
Even though some of them seem to be running testing or
unstable.

However I've noticed that there is also a:
deb http://ktown.kde.org/~nolden/kde/sid/i386 ./
Based on the URL this seems more appropriate...

Which one is the recommended one?

Many thanks for your help in advance!
best regards,
Balazs
